John Lincoln Mahon (8 June 1865 – 19 November 1933) was a Scottish trade unionist and politician, best known as a prominent socialist activist.
Mahon was born in Edinburgh, to Irish parents, with the surname "McMahon".Robert Page Arnot, William Morris, the man and the myth, p.76 He followed in his father's trade by becoming an engine fitter.Derek Fraser, A History of Modern Leeds, p.386
Mahon was an early member of the Social Democratic Federation (SDF), in June 1884 launching "The Social Reform Publishing Company", a venture that did not last more than a few months, but also leading socialist propaganda in Edinburgh.Thompson, E.P. (1996) 'William Morris: Romantic to Revolutionary' Merlin: London pg.350-1 However, instead of forming an Edinburgh branch of the SDF, they formed the Scottish Land and Labour League which affiliated to the SDF.Thompson, E.P. (1996) 'William Morris: Romantic to Revolutionary' Merlin: London pg.352 Mahon sided with William Morris when he seceded with a majority of the SDF executive to form the Socialist League.Thompson, E.P. (1996) 'William Morris: Romantic to Revolutionary' Merlin: London pg.359
In 1884, Mahon moved to London, where he served as the first secretary of the Socialist League. However, he stood down in 1885, and in 1887 and early 1888 he travelled the north of England. He authored "A Labour Programme" in 1888, with an introduction by Robert Cunninghame-Graham of the Scottish Labour Party, later said to be a blueprint for the formation of the Independent Labour Party (ILP) five years later.Thompson, E.P. (1996) 'William Morris: Romantic to Revolutionary' Merlin: London pg.525 With Henry Alfred Barker, he founded the Labour Union, which adopted the programme as its platform, and he served as joint chair of the party until August 1889.Barbara Nield and John Saville, "Barker, Henry Alfred", Dictionary of Labour Biography, vol.VI, pp.19-21
Mahon moved to Leeds in 1890, but found himself blacklisted from most jobs due to his political activism. After an abortive attempt to become an independent 'labour' candidate in the 1892 Leeds South by-election, he was a candidate for the ILP in Aberdeen North in the 1895 General election coming second winning 608 votes (12.8%).
In 1900, Mahon relocated to Dublin, working as a commercial salesman, strangely becoming involved in the Dublin Liberal Unionist Association.From Socialism to Liberal Unionism His son, John, was born in 1901, like his father was politically active and became a Communist, standing for election unsuccessfully in the 1949 St Pancras North by-election.John Mahon
Mahon returned to London in 1904, remaining there for the remainder of his life, although he stood for the Liberal Unionists in the 1906 General Election in the Dublin Harbour constituency taking 872 votes (19.33%) and losing to the Nationalist candidate. He supported World War I, and near the end of the war joined the social democratic National Socialist Party .
He was married to Swiss born Marie in the 1901 census he stated No Religion, while his wife was documented as a Calvinist.John Mahon 1901 Census, National Archives.
